Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a high-temperature-resistant anti-corrosion coating with self-healing properties and a preparation method thereof. Background technique [0002] The ship management system is complex and huge in number, running through each cabin. Among them, the thermal piping system is one of the most important components in the piping system, mainly including superheated steam pipes, saturated steam pipes, hot waste gas pipes, hot waste liquid pipes, high and low pressure drainage pipes, etc. These thermal pipelines have been in harsh corrosive environments such as ocean atmosphere, high temperature (200-600°C) and gas-liquid for a long time, and are prone to obvious corrosion phenomena such as high-temperature oxidation and immersion in seawater, and are prone to adverse phenomena such as foaming, cracking, and shedding. One of the most severely corroded parts; [000...
